Topic: Fastest Sync Speed (Read 7271 times)

I'm constantly hitting the wall with slow flash sync speeds. Australian light can be hard, harsh and brutal, and when there is no option but to shoot through the middle of the day, fill flash is often a must.

Low powered options are obvious, HSS with speedlights often save the day, but a true high speed sync camera body would be brilliant to enable full use of Einsteins etc. I'm quietly hoping for 500th on the upcoming 7D2. I appreciate and understand why higher sync speeds on FF bodies is technically challenging, but how about APS-C?

Other than leaf shutter MF DSLR cameras, is there anything around that has FAST sync speeds? I'd even consider a sub-APS-C sensor provided it was acceptably high quality. Fuji? Panasonic? Olympus? Or (gasp...) Nikon?

there is NO way a future 7D is gonna beat the flagship 1Dx in this realmyou can always go with odins and monolights for added punch and use whatever shutter speed you like(note i've only tested this on my elinchrom lights and i'm not sure if the odin combo will work on einsteins)

or just ganglight a ton of speedlights in HSS I usually go with a gang of 3 on one of thesethrough a 40" shoot through or into a silver brolly

Neuro, I have a G15 which is fun for happy snaps but definitely not commercial quality with its tiny sensor and challenging dynamic range. The highlights blow abruptly and mercilessly far sooner than my requirements demand. Pity, otherwise it's a very cool little camera.

Privatebydesign, you still have a 1D? Now there's a piece of history. I'd hang onto that...

I don't mean to belabor the obvious...but have you tried using some reflectors and diffusers? If your problem is too much light, seems to me that you'll get much better results taming it than trying to fight it. You won't have to worry about color balance problems, fill ratios generally magically "just work," you can easily get big, soft light, and it's all damned cheap.

Plus, your models are probably squinting. Give them some shade and they'll relax and open their eyes while you simultaneously soften the light.

Cheers,

Uhm... what about high-speed flash synch? I don't know if Canon flashes support this, but when using my SIGMA 610 DG Super I can set it to FP mode and then use pretty much any shutter speed I want. It works like a charm in situations just like you described. I must admit I don't know what the limitations on FP mode is, but I use it to lessen the harsh shadows on bright days when working with wide open apertures.I don't have any examples of this online right now, but if you are interested I can dig up some examples later tonight I think. Though I am sure the folks here will now what issues you might run into when doing things like that.

SLR's with 1/500 sync speed have at least one electronic curtain. Anything else with very high sync speeds either has electronic or a central shutter, such as the Fuji X100 - it can sync at up to 1/4000th of a sec, as long as the lens isn't wide open.

The 1D mk IV had its 1.3x sensor shutter capable of syncing at 1/300th of a sec, but that shutter doesn't move as fast as the 1D X shutter which covers the larger FF sensor in 1/250th of a sec. A shutter moving at the same speed as the 1D X's over a smaller 1.6x sensor could offer a sync speed of 1/400th of a sec.

You're absolutely right, these strategies should be a first choice. When use of reflectors and diffusers is not practical or possible, fill flash used intelligently and with affinity for the subject & environment can be a powerful creative tool. Often a combination of all three can deliver the best result in difficult conditions.

Yes, high-speed flash sync (HSS) is a godsend at times, and a 100% valid tool. But it's major limitation is vastly reduced output and extreme power consumption. My holy grail for this week is a body with meaningful high flash sync speed (excluding medium format bodies). Even 500th/sec is almost holy grail material. For the jobs I do, 200th/sec on the 5D3 is just not fast enough.

According to wikipedia: 'Due to its hybrid electronic/mechanical shutter, it is in fact possible to flash sync the D40 beyond its published 1/500 maximum sync speed up to its maximum shutter speed of 1/4000.'
